Virtually all public health authorities and medical associations worldwide recommend that children and adults receive a minimum (and maximum) level of fluoride. Children need fluoride to protect their permanent teeth as they are being formed. Adults also need fluoride to protect their teeth from decay.

Several people, especially those at higher risk of tooth decay, benefit from fluoride treatment. This includes individuals who have:

• Unhealthy snacking habits
• Poor dental hygiene
• No (or little) access to a dentist
• Diets that are high in sugars/carbohydrates
• Bridges, crowns, braces, and other restoration procedures
• A history of tooth decay (cavities)
